- The udev daemon should be started to handle device events sent by the kernel.
During bootup, the kernel can be asked to send events for all already existing
- devices, to apply the configuration to these devices. This is usually done by:
+ devices so that they too can be configured by udev. This is usually done by:
/sbin/udevadm trigger --type=subsystems
/sbin/udevadm trigger --type=devices
- - Restarting the daemon does never apply any rules to existing devices.
+ - Restarting the daemon never applies any rules to existing devices.
- New/changed rule files are picked up automatically; there is no daemon
restart or signal needed.
Operation:
- - Udev creates/removes device nodes in /dev, based on events the kernel
- sends out on device creation/removal.
+ - Based on events the kernel sends out on device creation/removal, udev
+ creates/removes device nodes in the /dev directory.
- All kernel events are matched against a set of specified rules, which
possibly hook into the event processing and load required kernel
- modules to setup devices. For all devices the kernel exports a major/minor
+ modules to set up devices. For all devices, the kernel exports a major/minor
number; if needed, udev creates a device node with the default kernel
name. If specified, udev applies permissions/ownership to the device
node, creates additional symlinks pointing to the node, and executes
